The direction of illumination, traditional down pointing, horizontal, or vertical up pointing can be specified at the time of ordering.

All Abet solar simulators are completely self-contained. The source, arc lamp power supply, control electronics, shutter, lamp, and optical compartment are housed in a single compact enclosure. A digital shutter timer allows internal or external control of the shutter. HEPA filtering assures a clean supply of cooling air into the optical compartment.

A number of spectral matching filters are available to add to all Abet full spectrum solar simulators. Full spectrum systems normally ship with a borosilicate condenser lens to minimize UV exposure. If UV output is required fused silica condensers can be substituted.
